Abstract
The present invention relates to a binary assay method capable of providing wide dynamic range, a high degree of precision and rapid processing times in which analyte is reacted successively with two independently determinable forms of solid-supported binding partner and also with a labelled ligand having affinity for the analyte or binding partner. The analyte concentration is determined from signals deriving from the resulting two forms of analyte-binding partner-labelled ligand systems by reference to a double standard calibration curve. A kit for use in the method is also disclosed.
